We recently updated our AV to epo agent 2.5.1.213 and virus scan v4.5.1 sp1. I know there are loads more scanning options in this release. After it was updated, people started to notice apps hanging on startup. IE 5.5 especially. It also slows mail down, depending on the settings for in bound outbound mail. Does this sound familiar to anyone, or anyone have any ideas?? Thanks
